3 INSTALLATION
3.1 General
This section describes the installation and infrastructure requirements for the FMA501.
Departure from the instructions contained herein may void any warranty provided by SRK.
The FMA501 has been designed to be mounted in a standard 19” rack frame, where it will
occupy 3 rack units. Due to the weight of this unit, rear supports are also recommended.
However, the amplifier may also be used in a free standing situation, so long as all other
requirements are met as below.
3.2
Environmental
The amplifier is intended for indoor use. The amplifier should be protected from rainfall and
direct sunlight, extremes of temperature and humidity and from conditions of high dust levels.
The amplifier shall not be operated at altitudes in excess of 3500m above sea level. The
amplifier must be installed on a flat, stable surface. The amplifier must be installed in the
upright position. The amplifier must be installed in a location free from vermin and the ingress
of other animals. The amplifier shall not be installed in locations prone to flooding. All
ventilation orifices must be clear to allow adequate air flow.
3.3
Electrical supply
The electrical supply to the amplifier must be of the voltage, form and frequency described in
the specifications. All electrical wiring must be carried out in accordance with local laws,
standards and regulations. If power supply voltages regularly fall outside specifications then
a voltage regulator must be installed between the supply inlet and the amplifier.
3.4
Earthing
Adequate earthing of the amplifier is vital to ensure long term reliability and user safety. The
electrical supply must be earthed, via the earthing pin of the IEC connector. In countries
where power outlet earthing is merely optional, an earthed outlet
must be used. See safety
notice at the front of this manual. A separate, independent, earth is required for the
amplifier/antenna system and must be connected to the earthing point indicated on the rear of
the amplifier. The cable used to connect the earth should be as thick as possible, with 8 AWG
being the smallest size acceptable. Where possible, broad earthing band should be used.
In addition to the earth connection to the amplifier, the outer conductor of the coax feed to the
antenna should be connected to the earth, as indicated below.
